A piston compresses a cylinder of gas doing 1220j of work on the gas. Doing this compression, the gas loses 370j of energy to its surrounding. What is the net change for the internal energy of the gas during this process?
The net change in internal energy of the gas is equal to the work done on the gas minus the energy lost to the surroundings.
Net change in internal energy = Work done on the gas - Energy lost to the surroundings
Net change in internal energy = 1220 J - 370 J
Net change in internal energy = 850 J
Therefore, the net change in internal energy of the gas during this process is 850 Joules.
To find the net change in internal energy of the gas during this process, we need to consider the work done on the gas and the energy lost to the surroundings.
The net change in internal energy (ΔU) is given by the equation:
ΔU = Q - W
Where:
ΔU = net change in internal energy
Q = heat added to the gas
W = work done on the gas
In this case, the work done on the gas (W) is 1220 J, and the energy lost to the surrounding (Q) is 370 J. Therefore, the net change in internal energy is:
ΔU = Q - W
= 370 J - 1220 J
= -850 J
The net change in internal energy of the gas during this process is -850 J.
